Abstract
Description
Technical Field
[0001] This utility model relates to the field of feeding mechanism technology, specifically a feeding mechanism for a horizontal insert machine. Background Technology
[0002] Horizontal insertion machines are key pieces of equipment in the electronics assembly industry, used to automatically and accurately insert packaged electronic components (such as resistors, capacitors, and integrated circuits) into designated holes on printed circuit boards (PCBs). The performance of its feeding mechanism directly determines the machine's insertion efficiency, accuracy, and reliability.
[0003] During the feeding process of the horizontal insertion machine, the tape reel is fixed on the feeder, and the tape is composed of a carrier tape and a cover tape. The tape is intermittently conveyed by the conveying mechanism. When it passes through the peeling mechanism, the cover tape separates from the carrier tape, exposing the components, which are then removed by the insertion head. The separated cover tape and the discarded carrier tape need to be promptly wound up and cleaned by the winding mechanism to avoid interfering with the feeding path and to ensure the continuity and stability of production.
[0004] Currently, most horizontal insert machines use a motor to directly drive the take-up shaft via rigid mechanical transmission methods such as gears, worm gears, or friction wheels in their feeding and winding mechanisms. This design has a major drawback: during the winding process, as the diameter of the feed strip on the take-up roller increases, the load torque also increases. Furthermore, due to issues like strip jamming, the take-up motor is prone to stalling, potentially burning out the motor or damaging transmission components. This leads to frequent equipment downtime for maintenance and reduced production efficiency. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a feeding mechanism for a horizontal insert machine, which solves the problems mentioned in the background section.
[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a feeding mechanism for a horizontal inserting machine, including a mounting plate, two guide plates fixed on the top of the mounting plate, guide grooves provided on opposite sides of the two guide plates, a rotating rod rotatably connected between the two guide plates, multiple conveying teeth fixed on the outer side wall of the rotating rod, a conveying motor fixed on one side of one of the guide plates, the output shaft of the conveying motor fixedly connected to the rotating rod, and an L-shaped support plate fixed on the top of the mounting plate; The L-shaped support plate has two rotating rods rotatably connected inside. Two winding wheels are inserted into the outer side of the rotating rods. A magnetic ring is fixed to the outer wall of the rotating rod. An iron ring is rotatably connected to the outer wall of the magnetic ring. A winding motor is provided above the mounting plate. Winding grooves are opened inside the two guide plates. Synchronous pulleys are fixed to the outer wall of the output shaft of the winding motor and the outer wall of the iron ring. The synchronous pulleys are connected by a synchronous belt drive.
[0007] Preferably, a pad is fixed to the bottom of the winding motor, and the pad is fixedly connected to the mounting plate.
[0008] Preferably, a plurality of connecting rods are fixed between the two winding wheels, and a baffle is screwed into the inside of the rotating rod.
[0009] Preferably, a fixing plate is fixed to the top of the mounting plate, a screw is fixed to one side of the fixing plate, and a limit plate and a clamping plate are respectively fixed to the outer side wall of the screw.
[0010] Preferably, arc-shaped guide plates are fixed at both ends of the guide plate.
[0011] Preferably, both the conveying motor and the winding motor are stepper motors.
[0012] Beneficial effects This utility model provides a feeding mechanism for a horizontal insert machine. Compared with the prior art, it has the following advantages: The feeding mechanism of this horizontal insertion machine is equipped with a winding motor, a magnetic ring, an iron ring, a winding wheel, a synchronous pulley, and a synchronous belt. During feeding, the winding motor is started, and the winding motor drives the iron ring to rotate through the synchronous belt and synchronous pulley. The iron ring drives the transmission rod and the rotating rod to rotate through the magnetic ring. In this way, the winding wheel rotates, winding up the cover tape and carrier tape of the electronic component material tape. After the conveyor motor stops, the synchronous pulley will rotate with the magnetic ring. This transmission method plays an overload protection role, effectively avoiding damage from the winding motor stalling, and can adapt to changes in winding tension, ensuring the reliability and stability of the feeding process.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figures 1 to 4 This utility model provides a technical solution: a feeding mechanism for a horizontal inserting machine, including a mounting plate 1, two guide plates 2 fixed on the top of the mounting plate 1, guide grooves 3 opened on opposite sides of the two guide plates 2, a rotating rod 4 rotatably connected between the two guide plates 2, multiple conveying teeth 5 fixed on the outer side wall of the rotating rod 4, a conveying motor 6 fixed on one side of one guide plate 2, the output shaft of the conveying motor 6 fixedly connected to the rotating rod 4, an L-shaped support plate 7 fixed on the top of the mounting plate 1, two rotating rods 8 rotatably connected inside the L-shaped support plate 7, two winding wheels 9 inserted into the outer side of the rotating rods 8, a magnetic ring 10 fixed on the outer side wall of the rotating rods 8, an iron ring 11 rotatably connected to the outer side wall of the magnetic ring 10, a winding motor 12 provided above the mounting plate 1, winding grooves 13 opened inside the two guide plates 2, synchronous pulleys 14 fixed on the outer side wall of the output shaft of the winding motor 12 and the outer side wall of the iron ring 11, the synchronous pulleys 14 being connected by a synchronous belt 15, which facilitates the winding of the cover belt and carrier belt after the material belt is split.
[0017] Furthermore, a pad 17 is fixed to the bottom of the winding motor 12, and the pad 17 is fixedly connected to the mounting plate 1, which can raise the height of the winding motor 12. Multiple connecting rods 18 are fixed between the two winding wheels 9. A baffle 19 is screwed into the inside of the rotating rod 8, which can block the winding wheel 9. A fixing plate 21 is fixed to the top of the mounting plate 1. A screw 22 is fixed to one side of the fixing plate 21. A limit plate 23 and a clamping plate 20 are fixed to the outer side wall of the screw 22, which can be used to mount the electronic component disk on the screw 22. Arc-shaped guide plates 16 are fixed to both ends of the guide plate 2, which can guide the material strip. Both the conveying motor 6 and the winding motor 12 are stepper motors, which can control the rotation of the motors.
[0018] During operation, the tape reel carrying the electronic components is first placed on the screw 22 of the fixing plate 21, and the reel is reliably clamped and fixed by rotating the clamping plate 20 to engage with the limiting plate 23. The starting end of the tape is pulled out, so that the two sides of the carrier tape are embedded into the guide grooves 3 of the two guide plates 2. During the tape's movement, the cover tape is on top and the carrier tape is on the bottom. The conveyor motor 6 is started, and its output shaft drives the rotating rod 4 and its conveying teeth 5 to rotate synchronously. The conveying teeth 5 engage in the gaps between the electronic components, and through precise step control, the tape is intermittently conveyed forward at a preset step distance. When the tape is conveyed to the arc-shaped guide plate 16 at the end of the guide plate 2, the cover tape and the carrier tape begin to separate. The cover tape is guided upward and wound onto the upper take-up roller 9, while the electronic components stripped of the cover tape are exposed in the carrier tape groove, waiting for the insertion head to pick them up. The carrier belt continues downwards, wrapping around the arc-shaped guide plate 16 and then onto the lower take-up roller 9. Simultaneously with the operation of the conveyor motor 6, the take-up motor 12 starts. The take-up motor 12, through a transmission system consisting of a synchronous pulley 14 on its output shaft, a synchronous belt 15, and a synchronous pulley 14 on the outer side of the iron ring 11, transmits power to the iron ring 11. When the iron ring 11 rotates, it drives the magnetically connected magnetic ring 10 to rotate synchronously via magnetic coupling. The magnetic ring 10 is fixed to the rotating rod 8, thereby driving the rotating rod 8 and its two take-up rollers 9 to rotate together, achieving synchronous and active take-up of the cover belt and carrier belt, ensuring... The tension of the material holding belt is stable during the conveying process. When the diameter of the cover belt or carrier belt on the take-up reel 9 increases, resulting in an increase in load torque, or when jamming occurs for some reason, if the resistance exceeds the maximum magnetic transmission torque between the magnetic ring 10 and the iron ring 11, the two will idle. This transmission method plays the role of overload protection, effectively avoiding the stall damage of the take-up motor 12, and can adapt to changes in take-up tension, ensuring the reliability and stability of the feeding process. The above process is repeated until the entire roll of material is used up. After the operator replaces the new material tray, the above steps can be repeated to achieve continuous automated production.
